Only if within sight of motor, using branch circuit breaker(a dedicated circuit breaker in panelboard for motor) as a disconnecting means is enough without additional safety switch regardless of motor horsepower for NEC code. Is that right?
NEC 430.109(A) shows that "molded case circuit breaker" can be served as a disconnecting means for motor.
However NEC 430.109(B)describe that "For stationary motors of 1⁄8 hp or less, the branch-circuit overcurrent shall be permitted to serve as the disconnecting means.
1/8 hp max if using a breaker. 430.109(A) is general conditions while(B) is specific. When I get confused on an article, I will read the entire article. Then I will "remove" all the paragraphs that do not apply to my situation then read it again. In this case if you only read 430.109,430.109(A), and 430.109(B), you ought to be enlightened.
